4612
4613         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning

4621
4622         Timer nodes are now reference counted, and can be marked
4623         as deleted. This allows for the safe release of the global mutex
4624         in the middle without losing the timer being operated on.
4625
4626         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4627         member is now an enum with three values, so that an intermediate
4628         state can be represented (deleted but not free for reuse yet).
4629         New refcount member added.
4630         * sysdeps/pthread/timer_routines.c: Likewise.

4634
4635         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
4636         restructured, recursive deadlock bug fixed.
4637
4638         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4639         timer_addref to ensure that timer won't be deleted while mutex is not
4640         held. Also uses timer_invalid to perform validation of timer handle.
4641         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4642         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4643

4653         manipulation code.
4654
4655         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):

4658         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4659         new return value from __timer_thread_queue_timer to avoid waking
4660         up timer thread unnecessarily.
4661
4662         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4663         inuse flag, because this requires mutex to be held.  Callers updated
4664         to do the check when they have the mutex.
4665         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4666
4667         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4668         regions: avoids making system calls while holding timer mutex, and
4669         a few computations were moved outside of the mutex as well.
4670         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4671
4672         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4673         to list_unlink_ip, meaning idempotent.  Pointer manipulation
4674         changed to get better better code out of gcc.
4675         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4676         version of list_unlink added here.
4677         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4678         function in all places: idempotent one for timers, non-idempotent
4679         one for thread nodes.
4680         * sysdeps/pthread/timer_settime: Likewise.
4681         * sysdeps/pthread/timer_routines.c: Likewise.
4682
4683 2000-06-13  Ulrich Drepper  <drepper@redhat.com>

4700         * Examples/ex6.c: Test return value of pthread_join.
4701
4702 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
4703
4704         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4705         (__pthread_spin_trylock): Implement.
4706         (__pthread_spin_unlock): Implement.
4707         (__pthread_spin_init): Implement.

4709
4710 2000-06-10  Ulrich Drepper  <drepper@redhat.com>

4719 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
4720
4721         * sysdeps/pthread/timer_create.c: Thread matching now done on
4722         clock type as well as thread attributes.
4723         There are individual global signal-delivering threads for
4724         different clock types.
4725         * sysdeps/pthread/posix-timer.h: Likewise.
4726         * sysdeps/pthread/timer_routines.c: Likewise.
4727
4728         * sysdeps/pthread/timer_routines.c: Thread allocation and
4729         deallocation function now remembers to put thread on active
4730         list and remove from active list.
4731         Thus now the feature of binding multiple timers
4732         to a single thread actually works.
4733
4734 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
4735
4736         * pthread.c (__pthread_create_2_1): Optimize a bit.

4743         * joinrace.c: New file.
4744         Reported by Permaine Cheung <pcheung@cygnus.com>.

4797
4798         * lockfile.c (__fresetlockfiles): Now also resets the list lock,

4811
4812         * linuxthreads.texi: Now explains what happens to streams at
4813         fork time. Also whole new section on forking and thread added.

4841
4842         Bugfix: The pthread_atfork mechanism now takes care of its
4843         own internal mutex at fork time.
4844
4845         * ptfork.c (__fork): Revised so that the mutex is held across
4846         the fork operation and while the handlers are called, and so that
4847         the child resets the mutex.
4848
4849         * linuxthreads.texi: Updated pthread_atfork documentation to make
4850         it clear that fork and pthread_atfork can't be reentered from
4851         atfork handlers, that pthread_atfork and fork are mutually atomic,
4852         and that the handlers are inherited by the child process.
4853

4896         object state is represented with additional bits which distinguish
4897         whether that state was set up in the current process, or
4898         in an ancestor process. If that state was set in an ancestor,
4899         it means that a fork happened while thread was executing the init
4900         function. In that case, the state is reset to NEVER.

4917         after unblocking main thread; wait for main thread's
4918         REQ_PROCESS_EXIT request instead.
4919         Also, added REQ_KICK case to handle new request; this just does
4920         nothing.
4921         * manager.c (pthread_exited): Do not terminate manager after
4922         unblocking main thread.
4923         * manager.c (__pthread_manager_sighandler): If the main thread
4924         is waiting for all other threads to die, send a REQ_KICK into
4925         the thread manager request pipe to get it to clean out the threads
4926         and unblock the main thread as soon as possible. This fixes
4927         the 2000 millisecond hang on shutdown bug.
4928         * Examples/ex7.c: New file, tests shutdown behavior when all threads
4929         including the main one call pthread_exit(), or implicitly do so.
4930         * Makefile (tests): Add ex7.
4931
4932 2000-05-05  Andreas Jaeger  <aj@suse.de>

5359         simultaneously.
5360         * restart.h: Restarts queue even on kernels that don't have
5361         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5362         avoiding a rare race condition in pthread_cond_timedwait.

6622         Since sigset_t no longer fits in a register, we can't pass in the
6623         thread's initial mask so easily.  Take this opportunity to simplify
6624         the clone implementation by only accepting a single void* argument.
6625
6626         * manager.c (__pthread_manager): Put thread vitals in the thread
6627         struct instead of as arguments through clone.
6628         (pthread_start_thread): Look for them there.
6629         * internals.h (struct _pthread): Add p_initial_fn,
6630         p_initial_fn_arg, p_initial_mask.  Fix __pthread_manager proto.
6631         * pthread.c (pthread_initialize_manager): Revise clone invocation.
